Patented Sept. 24, 1929 UNITED STATES PATENT OFFICE FRANK 3. BROWN, or DALLAS, TEXAS DEVICE FOR INKING STENCIDS IN ADDRESSING MACHINES Application filed November 25, 1927. Serial No. 235,682.

This invention relates to improvements in devices for inking stencils, particularly those of a cloth type, such stencils being used in adand blurs. The present device comprises an arrangement of parts wherein there is in-- cluded a roller co-acting with an inking wick and other parts wherein the roller is caused to move under and against each successive stencil in inking the stencil and thereafter the roller returns to normal position without coming in contact again with the stencil.

In the drawings:

Figure 1 is a longitudinal sectional view 0 the device.

Figure 2 is a plan view.

Figure 3 is a sectional detail view of an ink ing wick and ink container.

Figure 4: is an end View, taken from the ends 15 are curved over the rod3 to effect right in Figure 1; and

Figure 5 is a fragmentary detail end View partly in section of the device as shown in I when moved'to thedotted-line. position in so .30 Figure 1.

Proceeding in accordance with the drawings and wherein different numerals are em-' ployed to deslgnate the various parts, 1 denotes the side plates or walls of an inner frame enclosing the mechanism. The side walls are spaced apart by a rod 2 and a rod 3, more particularly referred to hereinafter. Screws 4 connect the inner frame to a larger frame I that as the roller 6 is'thrust upward and along (not shown).

In Figures 1 and 2 is shown a portion of an element 5 which is connected to a source of power included in an addressing machine in conjunction with which the present device is used. This member 5 carries a roller 6 loosely mounted on a pin 7 the latter passing through a yoke 8, thcends of the pin 7 being loosely mounted in the roller bearings 9.

On the inner sides of the plates 1 are tri angular-shaped members 10 connected to the side walls by rivets 11, forming a shelf or enable the roller to move in the direction of 5 trackway and projecting inwardly for a sufiicient distance to enable the bearings 9 toroll therealong. The periodical thrust of the member 5 carrying the roller 6 will thus the arrow in Figure 1, the roller moving upwardly to position 6', thence traveling to position 6"! In the last mentioned position the roller has dropped off the end of the shelf or members 10 and come in contact with the 00 inking wick 12, see Figure 3.

The inking wick 12 has contact with ink in the container 13 and includes a wick holder 14, the portion 14 thereof being curved over inwardly of the frame far enough to come in contact with theroller as it descends from the end of the shelf.

the latter moves from the position 6 to the position 6*,"in which case the plate 14" assumes the dotted-line position shown in Figure 1 at 14. This plate is under tension of a spring 15, wound around the rod 2, and the resiliency. i

" Attached to the rod 3 is a spring 16 which Figure lby the reciprocation of an element [carried on the adressing'machine, causes the These selector members need only to be tripped in order to start their operation which thes'pring brings about.

From the foregoing it will now be apparent 'since it is believed the operation of the device will be clear withoutthem. The roller will automatically descend upon the inking wick thence upon the plate 14. Since the plate isgunder tension of the spring 15, the

rollerwill be supported and yet allowed to roll downward. The roller bearings 9 then ride upon the under side of the shelf and will travel to the rounded ends thereof as shown at B, and under tension of the spring, after it goes beyond the shelf, will be moved upwardly as indicated by the arrow, in position for another cycle.

Particular attention is called to the fact that the plate 14 provides a means for dis- I tributing the ink over the roller, this being effected by the roller as it comes in contact I with the ink wick 12 then travels along the plate and causing the ink to spread and be distributed. This will be more apparent after considering that after successive trips of the roller over the ink wick and plate, more or less ink will collect. on the plate. The ink collected on the plate by the roller'thus enables the even distribution of ink over the roller. 7 I

What is claimed is:

1'. A stencil inking device for addressing machines, comprising a frame having a'shelf 'forming a trackway, a stencil inking roller movable upon the trackway; an inking wick; meansfor supporting the wick in the path of movement of the roller to ink the roller; a plate for distributing the inkon'said roller and for guiding the roller during a portion of its movement; means for holding theplate against the roller; and an ink receptacle for the Wick. I

2. A device as set out inclaim 1 and wherein said trackway is on an angular and a horizontal plane,- said roller moving upwardly toward the stencils to be inked and coming in contact with the stencil on a horizontal plane as the stencil is being inked; the roller traveling against the stencil in one direction onl device as set out in claim 1 and wherein said shelf forming said trackway is disposedabove said plate to enable said roller to travel on its return movement between the plate and underside of the shelf; the end of said shelf being curved to guide the roller in its ascent.

4. A device for inking stencils in connection with an addressing machine, comprising a frame having shelves comprising an upper and a lower trackway; a roller movable between and upon the shelves forming the trackway and arranged to come in contact with a stencil-on a horizontal plane; one end of the trackway stopping short of one end of the frame to permit the roller to move off the trackway; a plate pivotally supported below the trackwayv to support the roller on its descent from the upper trackway and forming means to cause the roller to travel between opposite sides of the trackway and assisting in guiding the roller on its return 7 movement. v

In testimony whereof I afiix my signature. FRANK B. BROWN. 7
